The address and sustain discharge characteristics in plasma display panels (PDPs) are investigated and compared by the optical emission spectroscopy using the ICCD and Vt close-curve analysis. The observations on the xenon (Xe) emission show that the spatial and temporal evolutions in the first sustain discharge are quite different from those in the address and the other sustain discharges. The striation found in the conventional sustain discharge doesn't occur in the first sustain discharge. These different discharge behaviors are explained by employing the Vt close-curve.

The characteristics of the reset and the address discharges of an alternating current Plasma Display Panel (ac PDP) were studied using 2-dimensional numerical discharge cell simulation. We investigated the wall charge variations during the reset discharge adopting ramping reset pulse and the subsequent addressing discharge. The roles of the ramping reset scheme can be divided into two stages, each electrode gathers wall charges during ramping-up of the initial stage and the built-up wall charges are lost during ramping-down of the later stage. Address discharge does not only change the wall charge distributions on the address and the scan electrodes but also on the sustain electrode. The increase in the wall charges on the sustain electrode was observed with the variation of the applied voltage to the sustain electrode during the address period. The increase of the applied voltage to the sustain electrode during the address period is expected to induce the decrease of the sustain voltage during the display period.

The ramp type bias voltage applied to the common electrode during a reset-period is newly proposed to lower the background luminance and to improve the address discharge characteristics in AC-PDP. The positive ramp bias voltage is applied during the ramp-up period, whereas the negative ramp bias voltage is applied during the ramp-down period. The effects of the voltage slopes in both the positive and negative ramp bias voltages on the background luminance and address voltage characteristics are examined intensively. It is observed that the optimized positive and negative ramp bias voltages applied to the common electrode during the ramp-period can lower the background luminance and also enhance the address discharge characteristics of the AC-PDP.

To improve the luminance and luminous efficiency of a surface-discharge alternate current plasma display panel, we analyzed the sustain discharge characteristics as the voltage of the address electrode In the study. As the results, when the address voltage is a half of the sustain voltage in the sustain period, the luminance and luminance efficiency are the highest. The luminance efficiency increased about 16.2%~20.8% compared with the conventional type.

The influence of the grooved dielectric layer on discharge and luminous characteristics has been investigated for various depths of the groove to achieve a high luminance efficiency AC-PDP operated at a lower voltage. We use the voltagethreshold curve technique and address delay jitters to explain the discharge characteristics. It shows that the surface discharge voltage rely on the depth of the grooved dielectric layer. Vertical discharge voltage remains almost the same as the groove depth increases.

To drive the high-image quality plasma displays of XGA and/or full-HD, we must effectively improve the driving waveform, which get the reset period for the stabilized control of wall charges, the address period to select discharge or non-discharge, and sustain period for luminance in 1 TV-frame, and also the display quality. To accomplish them, the development of the technology for the fast address discharge is required. In this paper, the correlation between the sustain-electrode gap and address discharge characteristics for the high-speed addressing was analyzed using the measurements of dynamic voltage margins. Results showed that the narrower the gap between the sustain electrodes, the narrower the with of the scan pulse became and a dynamic margin of data voltage of 29.2 V was obtained at scan pulse width of $1.0{\mu}s\;and\;V_{ramp}$ of 240 V for driving 4-inch test penal, which the gap between sustain electrodes was $65{\mu}m$.

The discharge characteristics of 3 electrcdes AC surface discharge plasma display were analyzed. For an unstable state of the discharge which appeared at the maximum discharge voltage, it is found that a parbal erase of the wall charge by the second discharge is a cause. Based on the second discharge, new operation margin considering the interrelation between the address discharge and the display discharge was defined and the validity of it was verified by the experiments. It is necessary to decrease the acklress pulse width for high-speed addressing. However, the operation margin of the ackIress pulse decreases as the pulse width of it becomes narrower. If the address pulse width is wider than l[ps], the operation margin of the display discharge is not related to the address pulse width. From the experimental result, image or 8bit 253 gray level was displayed on PDP with the cell structure of the HDTV class by using the high-speed address ADS drive methcd with pulse width of $1[{\mu}s]$ and the brightness of $560[cd/m^2]$ was obtained. ained.

This study is related to the realization of high speed address driving method for Full-HD PDP. The new self-priming addressing(SPA) driving scheme was proposed to improve an address discharge time lag, which utilizes the priming effect maintaining the priming discharge during an address period. In this study, the basic characteristics of the priming ramp discharge were investigated and optimize the reset pulse and priming pulse. It is noted that the address discharge time lag is significantly improved from 1.2[${\mu}s$] to 0.8[${\mu}s$] when the slope of the priming ramp pulse is below 0.1[$V/{\mu}s$].

In order to improve discharge characteristics in AC PDP, we suggest FDFA (Facing Discharge Front plate Address Electrode) structure. By adopting both long facing discharge electrodes and address electrodes in front plate, the FDFA structure make it possible to gain a high luminance, low power consumption, and a high luminous efficiency.

This research concerns the ADS drive method of 3 electrodes AC PDP and is determined the minimum pulse width of the address and the sustain, which the steady sustain discharge without decreasing luminance can be obtained. From the experimental result, if the address pulse width became $1.5[{\mu}s]$ or more a effective address discharge with the operating margin of 35[V] was possible. And if the sustain pulses width became $2[{\mu}s]$ or more, a steady sustain discharge with the operation margin of 25[V] was possible. When this condition is applied to Full-HDTV class PDP with the in lines of horizontal scanning lines, 8 sub-fields and total 1420 sustain pulses can be used.
